Featured Green stone snake ring

What do y’all think about this ring? Antique or not? What might the green stone be? The only mark is STERLING on the inside of the band. Thanks!!!
Sorry, I didn’t clean it well. That is green play-dough behind the snake head.

 

my 1st thought is jade... jadeite ..........

 

I doubt it's jade. Not sure what it actually is though. Maybe glass.

 

Ditto.

 

Thank you! What would be your guess in the age of the ring?

 

I was also thinking maybe a green agate? Anytime I don’t know what a stone it is, it always seems to be agate of some sort. I really do need a gemstone tester.

 

I'd say 1970's , but that's a guesstimate .....

 

Thanks! So definitely newer(ish).

 

I'd have to think so...... but always willing to be proven wrong !!!!!!

 

I'd think 1970s too.

I vote for Jade, too! would love to see it cleaned up!

 

Green agate is generally dyed a uniform green.

 

It could be 1970s, but I wouldn't rule out Arts & Crafts.
Could you show us the STERLING mark? I know insides of bands can be difficult to photograph, it works best of you put it down on a white piece of paper.
You can take a bigger photo and crop it. If you have trouble cropping it, one of us can do that for you.

 

I will try that later today when the sun is out. There is too much shadow now and the mark is not too clear.

 

I don’t know if this matters, but it a size 4. Sometimes I think smaller rings are older because people were smaller back in the day. But it could just be a small pinky ring.

 

That is 15 here in NL (diameter in millimeters), I agree, likely to be a pinky ring.
I am leaning towards Arts & Crafts.
Snake jewellery was very popular at the time, and the use of jadeite jade is more in keeping with the period and style.

 

Thank you!!
